This document provides instructions on how to make a diode appear that is currently not visible. It first instructs the user to physically pick up the diode if it is not appearing. It then notes that changing the diode's emission coefficient value to 0.01 may make it visible. The document also lists abbreviations for state of charge, battery voltage, and battery current.
